Title: Arithmetic circuit for cycle code
Inventor: SHIROMIZU YASUBUMI
IPC: G06F7/58
Filed: 1989-06-15
Abstract: PURPOSE:To attain the initialization of an arithmetic part and to decrease the number of component elements of an arithmetic circuit by stopping the clock of the arithmetic part in the arithmetic timing of the final bit and fetching the arithmetic result via a holding part. CONSTITUTION:A clock is inputted to a clock control part 3 together with a clock control signal which secures a higher level by an extent equal to the position of the final bit of an arithmetic range for the data changing synchronously with the rise of the clock. The arithmetic final bit is operated from the outputs of AND gates 31 and 32 and this arithmetic result is fetched by a holding part 2. Then an arithmetic part 1 is immediately initialized. Thus the part 1 is initialized before the operation is started for the head bit of the next operation without fetching the arithmetic result of the arithmetic final bit at the part 1. Thus it is not required to actuate alternately two circuits of the same constitution by switching them in a cycle where the arithmetic results of both circuits are taken out. Then the number of circuit component elements can be decreased.

Title: Transmission control method and device therefor
Inventor: SATO HIROAKI
IPC: H04L12/28
Filed: 1995-06-21
Abstract: PURPOSE: To prevent a received message from being carelessly repeated by switching either transmission system to an S and F mode when two transmission systems simultaneously start reception. CONSTITUTION: When an NCP reception part 45 detects the reception of a message from a transmission line 1, a message reception start detection signal 52 is inputted to an arithmetic unit 42, the mode switching circuit 47' of a transmission line 2 is controlled by a mode switching circuit control signal 51' and it is switched to the S and F mode. Thus, the received message is not bypassed through an NIF transmission part 48' only by transmitting it to an NCP reception part 45' even if an NIF reception part 49' starts the reception of the message.  Thus, a short or a long message is prevented from being carelessly repeated to the transmission line 2 while the device 42 checks the message received in the transmission line 1 and controls a transmission line switch circuit when the transmission line 1 simultaneously receives a self originating message and the transmission line 2 receives the message having a transmission line control function code whose data length is short.

Title: Electronic register
Inventor: UESUGI YOSHINORI
IPC: G07G1/00
Filed: 1978-12-15
Abstract: PURPOSE: To make it possible to set an arbitrary transaction limit amount to according contents of each item and inhibit transaction over respective set amounts by  items by providing a memory, an adder circuit, an FF, etc.  
     CONSTITUTION: The amount of memory for credit transaction is entered in B register 32. Then, the transaction limit amount read out from a memory is set to A register 31. Next, contents of A register 31 and B register 32 are sent to adder circuit 37, and the amount of memory for credit transaction in the B register is subtracted from the transaction limit amount in A register 31 to decide whether borrow is present or not. Unless borrow is present, FF39 is not set, and the Q'- side output is held in the "1" signal state, thus performing credit transaction registering. That is, if the amount of money for credit transaction is within the range of the transaction limit amount, FF39 is held in the reset state, and credit transaction registering is performed. If the amount of money for credit transaction exceeds the transaction limit amount and borrow is detected, FF39 is set. Therefore, the Q-side output of FF39 becomes "1", and transaction registering is inhibited.
